WHISTLING-PROPELLER TOY.

Application led July 8,

To all whom. t may concer-n.:

Be it known that FRANK H. NEwooMB, a citizen of the United States ofAmerica, residing at Ashland, in the county of Middlesex and State ofMassachusetts, has invented new and useful Improvements inlVhistling-Propeller' Toys, of which the following is a specifica-tion.v

The present invention has for its purpose to provide, in a toy of thiskind, a propeller construction with the lobes or blades oppositelypitched so that, when a twisting cord (on which the propeller isoperatively mounted) is pulled first in one direction and then theother, the propeller will act to displace the `air first in onedirection and then the other.

Another purpose "is to provide a whistling propeller toy, the lobes orblades of which are hollowT and provided with opposite aXially alignedopenings, the walls of the hollow lobes or blades being arcuate asshown, so that when the propeller toy is revolving first in onedirection and then the other, the hollow lobes or blades will draw inand expel the air and thereby create a whistling noise.

Still another purpose is to provide a to-y of this kind which willcreate considerable amusement for children and since the lobes orblades` are tinted in various colors, the whirling propeller will createan attractive and pretty aspect, especially in the sunlight.

. A further purpose is to provide al propeller toy of this kind whichmay be manufactured at a relatively small cost andsold at a reasonableprofit, said toy having opposite hub pieces through which the twistingcord or the like engages, opposite portions of the cord engaging throughspaced openings of the hub pieces so as to create a twisting action ofthe cord when the ends of the cord are pulled in one direction and thenrelaxed.

It is to be understood that the particulars herein given are in no waylimitative and that, while still keeping within the scope of theinvention, any desired modifications of detail and desired proportionsmay be made in the device according to the circumstances. l

The invention comprises further features and combinations of parts to behereinafter set forth, shown in the drawings and claimed.

In the drawings: v

vention and mounted 'on a twistinglcord, the loop ends of the cord beingshown in engagement with the fingers of an operator, and alsoillustrating the lobes or blades as provided with whistle constructions.i

Figure 2 is an enlarged detail view of the propeller toy removed fromthe cord, showing one of the lobes or blades in seetion.

Referring to the drawings, 1 designates a propeller hub which hasoppositely disposed radialpropeller lobes or blades 2.v These lobes orblades may be any suitable length and shape, preferably as illustrated,and are oppositely pitched so that, when the propeller toy is whirling,rotating first in one direction and then the other, it will displace theair first in one direction and then the other.

Each blade or lobe is hollow, as shown at 3, and the opposed walls 4thereof are arcuate. The opposed wallsV have laxially aligned circularopenings 5 and due to the whirling movement of the propeller toy, theopenings, due to the spacing and proper curving of the walls, draw inand'expel the air as the propeller toy whirls, therehv creating aWhistling noise.

Passing through and secured to the hub l are the opposite portions 7 ofan endless .loop of cord, twine. or similar .material The oppositeportions of the loop are engaged by the fingers of an' operator and thenthe propeller toy is first partially rotated by hand so as to partiallyvtwist the opposite portions of the vcord 0n opposite sides of the.propeller toy. Afterso starting,l the propeller toy and pgartiallytwistinjg the cord, the operator may then apply pulling action inopposite directions from the propeller toy and then relax the pull whichwill cause the opposite portions of the cord to twist and untwist andthereby cause the propeller toy to receive rapid revoluble movements.The propeller will act to displace the air first in one direction andthen the other and due to the drawing in and expelling of the airthrough the opposite openings 5 during the rotation of the propellertoy, a. whistling noise is created.

The invention having been set forth, what is claimed is:

1. As an article of manufacture, a whistling propeller toy comprising ahubpro' vided with radial blades oppositely pitched whereby thepropeller, upon receiving revino oluble movements first in one directionand then the other, expels the air first in one direction and then theother at right angles to the direction of rotation of the propeller, andan operating twisting cord. on which the propeller toy is operativelymounted and whereby, upon exerting pressure i-n directions away from thepropeller longitudinally of the cord and alternately relieving thepressure, revoluble movements are imparted to the propeller, theopposite walls of the propeller blades being'arcuate and provided withaxially alignedcircular openings which actto draw in and expel the airduring the rotation of'` the propeller for the purpose of creating aWhistling noise.

2. As an article or manufacture, a propeller toy comprising` a propellerhub provided with opposite radial blades which are hololuble action of te lpelled, thereby creating a whistling noise.

low and oppositel pitched, whereby a rev-.

ropeller will displace the air rst in one irection and then the other,and an operating twisting cord in an l endless loop with its oppositeportions passing through the hub of the propeller where- 25 by, uponexertin1r pressure in direction away from the propeller and thenrelieving the pressure, the propeller receives revoluble movements, theopposite walls of the hollow blades being substantially spaced cen- 30trally thereof and provided with axially aligned openings in the centersof the walls whereby, upon the propeller receiving revoluble movements,air is drawn in and ex- 35 In testimony whereof he aiixes his signature.
